An England-based photographer has captured some spectacular underwater photographs of American Crocodiles.
Wildlife photographer Chris Knight traveled to the village of Xcalak on Mexico's Caribbean Coast, near Belize.

He took photos of the crocodiles on a 'sweet-spot' shallow enough for them to stand in but deep enough to find prey.

He told Media Drum World: 'I have to say I was a bit nervous, but thoroughly excited at this unique opportunity. '
Knight first spent a few days diving in the area and learning about crocodiles.

He said: 'I ask the people that are running the trip for as much information as they can give me about the particular animal, its behavior and how I should act when I am in the water with it.
'Once I have a good understanding of the animal I will start to think about my camera settings.'
